THRESHER. n

Application led August 9, 1916.

To all whom t may concern Be it known that I, EDWARD VILLIAMS, a citizen of the United States, residing at Schuylerville, in the county of Saratoga and State of New York, have invented certain new and useful Improvements in rl`hreshers; and l do hereby declare the following to be a, full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to threshers and more particularly to a thresher which is designed for threshing` beans, peas or analogous agricultural products, and the primary obj ect of the invention is to provide a thresher which is constructed so that it will thresh dry beans, and thoroughly clean them without cracking them or breaking up the beans during the threshing thereof.

Another object of this invention is to provide a bean thresher which includes a novel beating structure for replacing the ordinary type ot' rotary cylinders and concaves used 2. in threshers, which rotary beating structure extends longitudinally of the thresher, so that the beans are fed into one end of the beater and travel therethrough, longitudinally ot the thresher and further to con- 1- 't struct the beater structure of an outer rotary shell which is provided with a foraminous outer wall and which rotates about an internally positioned rotary beater which has a plurality of angularly disposed vcleats :vformed upon the periphery of the same for engaging the beans and throwing them against the foraminous shell of the outer rotary member and also for directing them through the beating structure.

Another object of this invention is to provide a substantially frusto-conical shaped member which is attached to the receiving end of the internal rotary beater for preventing the bean pods from clogging about the shaft which extends centrally through the inner rotary beater.

Another object of this invention is to provide a grain pan which is positioned beneath the rotary beater structure for receiving the beans therefrom and which has suitable means connected thereto for vibrating the pan for carrying the beans rearwardly over its surface and further to provide a second vibratory grain pan structure which receives the partially threshed beans from the delivery end of the rotary beater struc- Specification of Letters Patent.

ture, and shakes them, and deposits them upon a vibrating riddle which in turn delivers them to a second riddle, andlinV turn to a delivery trough.

A still further object of this invention is to provide means for vibrating the delivery trough for preventing the beans from clogging the trough and to insure their passage through the same.

A still further object of this invention is to provide means for blowing the chaff or crushed pods out of the rear end of the thresher which means includes a rotary fan and adjustably mounted guiding nozzles for directing the direction of travel of the air blast.

1With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

ln describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which Figure 1 is a side elevation of the improved thresher.

F ig. 2 is a top plan view of the thresher.

Fig. 3 is a longitudinal section through the thresher.

Fig. 4 is a section on the line 4.--4 of Fig. 3.

Fig. 5 is a section on the line 5 5 of Fig. 3.

Fig. 6 is a fragmentary bottom plan of the thresher, and

Fig. 7 is a detail view of the internal rotary beater.

Referring more particularly t0 the drawings, 1 designates the supporting frame of the thresher which has front and rear aXle structures 2 and 3 respectively carried thereby, upon which are mounted the usual type of supporting wheels 4. The supporting frame l has a plurality of arch supporting braces 5 connected thereto and extending upwardly therefrom which braces form supports for the cover 6 that protects the working parts of the thresher. The foremost and rearmost arch brackets 5 have cross braces 7 and S carried thereby upon which are mounted suitable bearings 9. The bearings 9 rotatably support a shaft l0 which extends longitudinally through the center of the rammed Feb. 19,1918. i

shaft 10.

fthresher .andfhas'a rotary beating member 11 mounted thereupon atY the forward receiving end of the threslie-r'. The rotary 'beater wh'ch is generically indicated by the numeralll comprises a pluv.

'ral/ity of plates 12 whichare disposed angularly With-respecttoeachother as clearly shown in Fig.v 4 of theV drawings.,V The plates 12. are attached to end pieces 13 and 14 by bolts or analogous fastening devices as indicated at 15. The collars or disks 13 and 14 have hubs 17 which are mounted upon the Cleats 18,V are attached'to the outer surfaces ofthe plates 12 kand they incline toward the rear delivery end vof the thresher as Clearly shown in the drawings.

Y in Fig. A4 vof the drawings and the perforations in the plates 23 are of suiiicient size so as `to'permit beans which have been tlioiV oughly threshed to pass therethrough and also to permit sand and ne particles of pods or other foreign matter-to fall through theropening, upon the vibration panV structure 24.

The end rings 21 of theV shell beater Ahave spurs or teeth 25 attached thereto at spaced intervals about their periphery, which teeth are prov-ided'for engagementwith the links of sprocket chains 26. rlhe`V sprocket chains 26 also travel about .sprockets 27 which areV mounted upon a shaft 28.- The shaft 28 eX-l tends longitudinally ;along one side ofthe supporting frame 1 andhas a sprocketV 29 mounted thereon about which a sprocket y sprockets 27.

chain 30 travels. The'sprocket chain 30 also travels about a sprocket 31 whichY is carried by the shaft 10. In this manner the rotary shell beater is rotated by the rotation of the Vshaft 10 ata much slower rate of speed than is t-he internal rotary beater 11 rotated, owing' to the fact that the end rings 21 and 22 of the outer or Yshell beater structure are considerably The outer rotary beater structure 20 guided in its rotary movement by suitable' guiderollers 32 and 33 which engage the periphery of rings 34; which are positioned outwardly from the rings 21 and 22. The rollers 32 and 33 rotate idly upon stub shafts 'which are carried by the supporting structure of the thresher. s

Theends of the outer rotary beater 20 are open, anda feed board'36 is provided for Vguiding the beans to be threshed vdownwardlv into-the .interior of the outer shell like .rotary beater 20. A substantially frustoconically shaped block 37 is mounted upon vare carried by the pan structure.

greater indiameter than thev Vthe shaft 10 and engages the forward end of the inner rotary'beater structure 11, proriding 'anV inclined surface for 'preventing the beans from clogging or becoming hung Vonfi'ihe front end of the inner rotary beater Y structure, and properly guiding them li-n- Y substance from the threshed beans.- The pan structurev 24 is supported by hangers 39 vwhich Vhave their upper.v Vends rockably mounted in suitable journals40 and their lowerl ends connected to bearings 41 which *Y Rods 42 are also connected to the bearings 41 and to' the wrist portion 43 ofa' crankshaft 44. The crank shaft 44 is supported by suitable bearings 451 and itY has 'a pulley 46mounted Y thereon for rotatingV the shaft and conscquently vibrating the pan-structure 24.

Thel beans afterV they have rtraveled tlirouglrthe lengthrof the beater structure are guided' bya guiding ring 47 upon a pan structure 43 w iic'h vhas a corrugated surface as clearly shown in Fig.4 3 of the drawings. The pan structure 43is mounted for vibratory movement, so that thebeans deposited tliei'eoirivill travel over the full length of the same. Y Y

rThe corrugated.surface ofthe pan structure 43 is perforated, so that beans will fall.Y therethrough and theyA `are guided downwardly by a guiding board 49, and deposited upon the rear end of the pan structure 24. The pan structure 48 is coiineotedvto the pan Y structure 24 in any Vsuitable manner, for

vibratory movementl therewith. This may Vbe accomplished .by earswhich extendupf wa'rdly from the rear delivery end of the Ypan, structure 24r and are'conne'cted to the` pan, structure 48.-V

The beans are delivered bythe pan struc-Y ture 24 upon a sieveV or riddle 50 which in,V

clines upwardly7 as clearly shown in Fig.` 3

Aof the drawings, and the threshed beans will fall through the riddle 50 upon second ride dle or screen 51 which is positioned beneath the screen'or riddle 50 and inclines downwardly. A corrugated riddleY 52V is posi-Y tioned beneath the' AdeliveryY or lower `end Y of the vriddle A51 and it is provided with Vrelatiyely small perforations53 which are provided for permitting ineparticles of sand or foreign matter to fall therethrough. The beans travel off the surface of the coi-- rugated riddle upon the upper surface of the bottom V54 ofthe shoe and downicoy wardly over this surface into the delivery Y trou-gh 56. Y.

The riddles 50, 51 and 52 arecarried by 1 the shoe` 55,.andthis shoeis supported byV nary construction positioned therein.

and the riddles or screens carried thereby will be vibrated for facilitating the threshing and cleaning of the beans. The eccentric is constructed so that the riddles 50, 51 and 52 will be agitated faster than the pans 24 and 48 are agitated.

A fan casing 68 is carried by the under surface of the supporting structure of the thresher and it has a rotary fan 64 of ordifan casing 68 extends entirely across the width of the-thresher as does the fan 64, and the outlet 65 of the fan casing is directed toward the shoe 55. A nozzle 66 is adjustably connected to the outlet 65 of the fan casing 68 and it projects into the shoe 55, for directing` the air blast from the fan into the shoe for blowing the chaff or Ene particles of pods out of the shoe and into an ordinary blower structure which may be attached to the rear end of the thresher. 1n the drawings, no blower is illustrated, but it is to be understood that any ordinary or desired type of blower or stacker may be attached to the rear delivery end of the thresher without departing from the spirit of this invention.

The nozzle 66 is adjustably connected to the outlet 65 of the fan casing, so that it may be pivotally moved for directing the air blast in an upward path or in a relatively downward path, as desired, and as is found necessary under' different conditions.

The trough 56, into which the cleaned and threshed beans are delivered from the shoe 55, inclines downwardly, toward its delivery end and it extends entirely across the width of the thresher, having its delivery end positioned outwardly of one side of the thresher for delivering the beans into a sack or other suitable receptacle.

A bell cra-nk arm 68 is pivotally connected as shown at 69 to a cross beam 70, and its relatively short arm 71 is connected as shown at 72 to the under surface of the trough The long arm 7 3 of the bell crank arm 68 is pivotally connected as shown at 7 4 to an arm 75. rlhe arm 75 is connected to the under surface of the shoe 55 as shown 'at 76, so that upon the vibratory movement of the shoe 55, the bell crank arm 68 will be rocked upon its pivotal point 69 which will vibrate the trough 56 in a direction laterally of the movement of the pan, for shaking the beans out of the trough and preventing their clogging the same.

The

A relatively short shaft 78 is .rotatably supported by a suitable bearing 79, and it has a bevel gear 80 mounted upon its inner end which meshes with a bevel gear 81 mounted upon the shaft 10, for rotating the shaft 10 by the rotation of the stub shaft 78. A pulley 82 is mounted upon the outer end of the shaft 7 8 and the power belt 88 travels about this pulley. The power belt 83 also travels about a pulley 84 which is mounted upon the shaft 59, about a pulley 85 which is mounted upon the propelling shaft 86 of the fan 64, about the pulley 46 which is mounted upon the crank shaft 48, and it may travel about the drive pulley of a suitable traction engine or prime mover. 1t will be seen, by the foregoing and the drawings, that only one belt is employed for operating all of the various pulleys of the thresher.

A bevel gear 88 is mounted upon the shaft 10 adjacent to its rear end, and it meshes with a second bevel gear 89 which is carried by a shaft 90. The shaft 90 extends downwardly at an angle from the shaft 10 and it is supported by suitable bearin gs 91 which are formed upon a bracket 92. The shaft 90 is provided for propelling a blower of ordinary type.

rl`he operation of the improved thresher is generically as follows: The beans or other agricultural products to be threshed are deposited upon the feed board 36, which will. guide them inwardly into the outer rotary beater 2O and they will then be engaged by the angularly disposed cleats 18 which are carried by the outer surface of the inner rotary beater 11, and thrown outwardly against the perforated plates 23 of the outer rotary beater 11. rhis operation will be repeated a number of times, during the passage of the beans through the beater structure which will tend to break up the pods, and free-the beans therefrom. The inclined position of the cleats 18 will guide the beansv rearwardly during the rotation of the beater, until they are deposited out of the delivery end of the beater structure, through the guiding ring 47 upon the vibratory pan 48. The vibration of the pan 48 will carry the beans over the corrugated upper surface of this pan structure and tend to shake the beans and parts of the pods therethrough upon the guiding boards 49 which will guide them downwardly and toward the forward end of the machine for deposit upon the rear delivery end of the pan 24. The vibratory movement of theV pan 24 will deposit the beans therefrom upon the vibratory riddle 50. Certain of the beans will pass through this riddle upon the riddle 51, and the thoroughly 'threshed beans falling through the riddle 51 upon the upper surface of the bottom 54 of the shoe 55 will travel downwardly over this surface into Athetrough- 56. The beanswvhich travel over theV entireiupper surface of the riddles 50l and l Willbe deposited upon the corrugated riddle 52 and the vibration of this Y structure.

The beans which are thoroughly threshed during their travel through thebeaterstructurcs 'will p; is outi'rardly through the perleratieus in tlieplates 23 and fall upon the upper corrugated surface of the pan structure 2l. rThe pcrforations in this pan structure will permit sand orl other foreign inatl'er to fall through thev riddle upon the ground, and be eilicieiitly separated from the beans while the beans will be carried rearwardly, by the vibration of the pan Strucl'ure'and deposited uponthe riddle 50 together with the beans which are deposited upon the rear end of the pan structure 49 froin the pan structurelS.

The ribratery inovenient of 1the Vdelivery trough will prevent the beans from cloggingrtherein and insure their passage out of the trough into a'suitable retaining sack orv receptacle.

lironi the foregoing description taken in con nection with the accompanying drawings,

Y the advantages of construction and of the method of operation of the improved thresher will be'readily'apparent to those skilled in the arl-ato which this invention Y appertains, and while in they foregoing description, the Vprinciple ofthe operation of this invention has been described `together `with various features of construction,.ilJ isV to be understood that Certain minor features of construction, combination 'and' arrange-` ment of parts may be altered to suit practical conditions providedsuch alterations are comprehended Within the scope of what is claimed.
